When two boats share the same hull type — in this case both the Parti Kraft PK 1770 2011 and the Parti Kraft PK 2086 2012 are pontoon designs with aluminum construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Parti Kraft PK 1770 2011 measures 17,0 feet overall (2011), giving it roughly 15,0 additional feet of deck space compared to the Parti Kraft PK 2086 2012 at 2,0 feet (2012). Weight tells a clearer story for trailering families: the Parti Kraft PK 2086 2012 tips the scales at 2 318 lbs — 2 192 lbs less than the Parti Kraft PK 1770 2011 at 126 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 90 hp, the Parti Kraft PK 2086 2012 has a 30-hp advantage over the Parti Kraft PK 1770 2011's 60-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Parti Kraft PK 1770 2011 is rated for 8 passengers, while the Parti Kraft PK 2086 2012 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Parti Kraft PK 1770 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Parti Kraft PK 1770 2011 comes in at 2 lbs per hp versus 26 lbs per hp for the Parti Kraft PK 2086 2012. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
